Japanese designer Yusuke Kagari starts out with pristine, varnished leather, then uses concrete texturing tools and other distressing processes to make the material look like something out of a post-apocalyptic future. Each one of his bags takes about two weeks to create. Kagari draws inspiration from the long-term effects of wear and tear on old buildings in his native Tokyo. One series of bags, for example, is made to look like a rusted outwall.
